SPECIFICATION forming part of Letters Patent No. 635,432, dated October 24, 1899.

Application filed July 2 8, 1 89 9 To all whom it may concern:

Be it known that 1, WILLIAM DOYLE, Jr, a citizen of the United States, residing at New York, in the county of New York and State of New York, haveinvented certain new and usef ul Improvements in Door'Fastening Devices, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to bolts or fastening devices for doors; and the object thereof is to provide an improved device of this class by means of which a door may be securely locked or held closed and also held partially open or ajar whenever desired.

The invention is fully disclosed in the foltially open in dotted lines.

In the drawings forming part of this specification I have shown at 5 a part of a door and at 6 a part of the frame, and in the practice of my invention I secure to the door a plate 7, provided with a longitudinal tubular keeper 8, which does not extend to the end edge of the door, but terminates at predeter-' mined distance therefrom, as shown at 9. I also secure to the frame 6, at a predetermined distance above the plate 7, aplate 10, having a tubular keeper 11 open at both ends, and parallel with the keeper 8 and below the plate 10 and keeper 11 is a vertically-arranged keeper 12, between which and the frame of the door is an oblong space which extends between the points 13. I also provide a bolt consisting of a horizontal portion 14:, which is placed in and adapted to move in the tubular keeper 8, and an angular portion 15,connected therewith and provided at its end with an angular projection 16, parallel with the main portion 14 of the bolt and adapted to enter the keeper 11 or the keeper 12.

When it is desired to lock the door and Serial No. 725,347. (No model.)

hold it in the closed position, as shown in Fig. 2, the bolt 14. is slid back in the keeper 8, and the angular portion 15 thereof is turned upwardly, and said bolt is moved outwardly until the angular end projection 16 passes into the keeper 11, as shown in full lines in Fig. 1. This will securely hold the door in the closed'position, and whenever it is desired to partially open the door, but to prevent it from being entirely opened,as shown in dotted lines in Fig. 2, the bolt 14 is moved backwardly in the keeper 8, the angular extension 15 thereof turned downwardly, and said bolt is again moved outwardly, so that the end projection 16 will pass within the keeper 12-, as shown in dotted lines in Fig. 1. position of the bolt the door may be partially opened, as shown in dotted lines in Fig 2, but cannot be opened far enough to permit of a person passing in or out, the extent to which the door may be opened being regulated by the length of the angular extension 15 of the bolt 14. In this operation the angular projection 16 at the end of the angular extension 15 of the bolt 14: moves up and down in the keeper 12, as will be readily understood, and I thus provide a simple and effective look by means of which a door may be locked in the closed position and also held free to swing to a certain extent.

Although I have shown and described my improvement as a lock or fastening device for doors, it will be apparent that the same maybe applied to gates, windows, and other hinged articles as well as to doors, and many changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a lock or fastening device for doors, gates and the like, a slidably and revolubly mounted bolt connected with a door or gate, and a plurality of keepers connected with a frame orpost one above another, and each of which is adapted to receive one end of said bolt and in one of which said end of said bolt is adapted to move vertically, substantially as shown and described.

2. The combination with adoor or gate, of

In this a bolt slidably and revolubly mounted and provided at its outer end with an angular extension, and keepers secured to a frame or post one above another, both of said keepers being adapted to receive the angular extension of said bolt and one of said keepers being oblong in form so that said extension will move vertically therein, substantiallyas shown and described.

In testimony that I claim the foregoing as :0 my invention I have signed my name, in presence of the subscribing Witnesses, this 26th day of July, 1899.
